ARTHUR ROBERTS, OF EVANSTON, ILLINOIS, ASSIGNOR TO AMERICAN COKE &

CHEMICAL COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF MAINE.

COKE-.OVIEN HEATING WALL AND-THE LIKE.

To all whom it may concern:

Be it known that I, Amman ROBERTS, acitizen of the United States, residing at Evanston, in the county of. Cook and State of Illinois, have invented certain new and useful Improvements in Coke-Oven Heating Walls and the like, of which the following is a specification.

The present invention has to do with certain improvements in the construction of coke oven heating walls, although .it will presently appear that the features of the invention are in nowise limited to use in connection with heating walls, but may also be applied with equal advantage to other forms of coke oven wall.

In Letters Patent of the United States, No. 1,132,685, which was issued to me March 23, 1915, for improvements in coke ovens, have shown a construction of coke oven wall which isv provided on its interior with a meshwork of interconnectedgas passages of such formtthat the gases traveling therethrough are caused to deflect back and forth in a zigzag manner as they travel through the wall, thereby being driven with violence against the wall and caused to impinge thereagainst. In the particular construc-' tion illustrated in the said Letters Patent, I have shown also a convenient form of block, from which to build or construct the walls so as to obtain the aforesaid meshwork of impingement passages. The present invenan improved type of heating wall construction, and also the construction of the notched blocks for the same.

One of the objects of the present invention is to improve the form of the notched block so as to thereby cut down or diminish the frictional resistance of the gases as they pass through the wall. Another object is to provide a construction of block which can be very economically moulded and manufactured, thus reducing the cost of construction very materially,

Other objects and uses of the invention Will appear from a detailed description of the same which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referring to the drawing:

Figure 1 shows a. vertical fragmentary section through a portion of the heating wall built up from blocks of the form here- .in disclosed, being a section taken on the Specification of Letters Patent,

and 8 on its side Patented Jan/17, 1922.

Application filed January 27, 1919. Serial No. 273,229.

linel-l of Fig. 2, looking in the direction of the arrows; i

Fig. 2 shows a fragmentary horizontal section taken on the ing in the direction of the arrows;

Figs. 3 and 4 respectively show plan and side elevations of one of the key-stone blocks of the form herein disclosed; and

Figs. 5 and 6 show plan and side elevations of one of the intermediate blocks of the form herein disclosed. I

The heating wall herein disclosed comprises a series of courses, each formed or built up from notched blocks of the detailed construction shown in Figs. 3, 4,- 5, and 6. Each block is shown as being recessed at 7 faces, so that, when two of the blocks are placed together side by side, the vertically extending gas passages 9 are thereby produced, said passages being equal to the combined width of the adjacent notches 7 and 8.

ne adjacent face of each block is also notched as at 10, so that when the courses are set together, horizontal passages will be provided by way of said notches 10.

The upper portion of each block is tapered or made of V-shaped formation 'as at 11, so as to split the gas streams and thus reduce the resistance to the flow of the gases.

It is to be observed that the notches 10 are in one of the horizontal faces of the blocks, and that the tapered or V-shaped portions 11 are in the upper faces of the blocks. As a convenient form of construction, the notches 10 may be placed in the upper faces of the blocks, and the tapered or V-shaped portions 11 may also be formed in said faces. This is the construction illustrated in the drawing, but it will be understood that it is not necessary that the notches 10 should be in the upper faces.

While I have herein shown and described only a single embodiment of the features of this invention, still it will be understood that I am not limited to the said features, except as I may limit myself in the claims.

I claim:

1. A coke oven heating wall comprising horizontal courses of blocks, the blocks of consecutive courses breaking joints with each other, each block having its sides recessed to thereby reduce the width of the central portion of the block, and having its top portion recessed to thereby provide a horiline 2-2 of Fig. 1, looki zontally extending passage beneath the block above it, said top portion being tapered or Wedge-shaped, whereby the side recesses of adjacent blocks cooperate to provide vertically extending passages between the blocks in communication with the aforesaid horizontally extending passages, and whereby the tapered top portions of the blocks serve to split the gas streams and prevent the accumulation of deposit on the top portions of the blocks, substantially as described.

2. A coke even heating wall comprising courses of blocks, the blocks of the consecutive courses breaking joints with each other, there being side recesses in the blocks serving to provide vertically extending passages between the blocks of the courses, and there being top recesses in the blocks serving to provide horizontally extending passages between the blocks, the top portions of the blocks being tapered, whereby the gas streams are split and whereby 'the accumulation of deposit on the tops of the blocks is prevented, substantially as described.

3. A coke oven heating wall comprising courses of blocks, the blocks of the courses breaking joints with each other, there being side recesses in the blocks serving to provide vertically extending passages between the blocks, and there being tapered top faces on the blocks serving to ensure communication of the vertical passages of one course with the vertical passages of the course above, and serving to split the gas streams blocks, substantially as described.

ARTHUR ROBERTS.
